Specification of Letters Patent.

Application filed June 18, 1914. Serial No. 845,921.

To all whom it may concern:

Be it known that 1, JOHN F. AsHLnY, a citizen of the United States of America, residing at Graham and Sante Fe streets, Dallas, Texas, have invented certain new and useful Improvements in Hoeing-Vlachines, of which the following is a specification.

This invention as specified relates to new and useful improvements in hoeing ma chines.

The object of the invention is to provide a machine of the character described which will embody a novel and eilicient form of double drive; said machine being driven from the two corresponding side transport wheels which makes possible a st night and even drive down the row eliminating side draft.

Another object is to provide a single hoe machine which will have a natural, smooth, easy and unvarying stroke as it passes through the row.

A further object resides in the provision of means for varying or adjusting the length of the hoe arm.

Finally the object is to provide and develop a hoeing machine of the character described which will be strong and durable, comparatively simple and inexpensive to manufacture and one whoseworking parts will not be likely to get out of working order.

WVith these and other objects in view the invention has relation to a certain arrangement and combination of elements, an example of which is described in the specification, pointed out in the appended claims and illustrated in the accompanying drawings wherein;

Figure 1 is a plan view of the hoeing machine correlated with a portion of a carriage, cultivator, or other form of implement upon which the hoeing machine may be mounted; only the portion of said cultivator being necessary to show the attachment of said hoeing machine being herein illustrated. Fig. 2 is a rear elevation of the hoeing machine correlated with a portion of a cultivator. Fig. 3 is a sectional view taken upon the line a-a of Fig. 1 illust 'ating the form of one of the driving members of the hoeing mechanism. Fig. 4 is a side view of the adjustable hoeing arm. some parts being shown in section. Fig. 5 is a View taken upon the line b b of Fig. 41.

Referring now more in particular to the drawings, wherein the same reference char acters designate identical elements throughout, the numerals 1 and 2 respectively designate a cultivator transport wheel and arched axle; the vertical portion of said axle being referred to by numeral 3. Substantial horizontal support brackets i with vertically upturned portion 5 are rigidly mounted by U bolts (3 to the axle portion 3. A reach bar T is lined. adjacent and parallel to the axle, to the support brackets and :ulaptcd to stiffen the structure and support elements hereinafter mentioned.

drive shaft 8 is journalcd in bearings and 10 fixed to the support brackets 4. Said shaft carries fixed to each extremity pinions 11 and 12 which mesh with gears 13 and H fixed to the transport wheels by U bolts 15. A drive gear 16 is fixed to the shaft 8, said gear being provided with a ratchet toothed hub 17. Said toothed hub is adapted to normally engage a slidable toothed out? 18. A key Way 19 is formed in the cull 1S and adapted to engage a key 20 fixed to the shaft. The cufl" 18 and drive gear 16 are hollow bored as indicated by the numeral 21. A coil compression spring is confined upon the shaft and within the hollow portion 21 which subjects the engaged gear and cult to a parting thrust. The pinion 11 has a toothed engagement with a toothed cufl 23. A key 23 fixed to the shaft provides a sliding disengagement for the coil 23. Said engaging members are hollow bored, a coil compression spring 24- subjects them to a tendency of disengagement. The bearing 10 is formed with flanges 25 and recessed portions 26. A pair of vertical lever members 27 having eyes 28 are carried by the shaft 8 and disposed upon either side of the bearing 10 having their adjacent edges lying contiguous with the flanges of the bearing 10. One of the levers is provided with a horizontal arm 29 which passes through a slot 30 in the other lever member. A tube 31 is carried by the shaft and has its extremities lying contiguous with the out]? 18 and one of the lever members. The arm 99 is provided with a handle 29.

It is seen how the compression of the two springs 22 and 24 will thrust the eyes inward toward the recessed portions fit. It is further seen that the pair of vertical levers unified in. relation and may be pivoted forward about the shaft as a center. A forward displacement of the levers, through a slight pressure on the handle 29, will cause the vertical lever members to be disengaged from the flanges 25 and cause the eyes 28 to drop within the recessed portion, which action disengages, through the pressure of the springs, the two slidablc cuii" members from the gear and pinion. This action as seen disengages the driving relation over the shaft 8 of one of the transport wheels While the other wheel will continue to drive said shaft.

It should be understood that a hoeing machine to be practical should be driven from both wheels, this being necessary to eliminate the side draft. This being the case it becomes necessary to provide one of the driving wheels with a device to cut off its driving relation when turning corners, to prevent undue strain on the driving mechanism. A support frame, composed of a pair of horizontal brackets 33 fixed to the reach bar and extending forward and carrying an angle member 34%, is provided to carry the hoeing mechanism hereinafter described. A shaft 35 is ournaled in bearings 36 and 37 carried by the members 34: and 7. A pinion 38 is fixed to one extremity of the shaft 35 and engages the gear 16. The shaft extends forward through the angle member 34 and has fixed to its extremity a crank arm 39. A vertical support arm 41) is substantially fixed to the angle member 7 and is provided with bracket 41 which bracket and support arm carries a pinlQ. A substantially vertical gyrating arm 43, provided with a slot 44, is carried by the pin 42. Said arm is provided with a slot 45 formed in its lower extremity. A hearing bracket 46 is fixed to the gyrating arm and connects with the crank arm 39, thereby, establishing a movable relation with the gyrating arm.

A hoe arm 4:? is correlated with the gyrating arm and provided with means of adjustment in length. Said hoe arm is provided with a cutting blade and slotted as indicated by 48. A rib 49 is fixed to the gyrating arm and lies within or engages the slot 4:8 of the hoe arm. Guide sleeves 50 are fixed to the gyrating arm 43 and adapted to slidably retain the hoe arm in a close and stiff relation with the gyrating arm yet allow it, as seen, to be subjected to a sliding adjustment within the sleeves and upon gyrating arm. To effect the adjustment of the hoe arm a substantially long vertical adjustlng lever 51 is provided, said lever has formed on its lower extremity an outturned portion 52 which passes through the slot a5 and is fixed in an aperture in the hoe arm by a pin 53. The lever extends upward and is provided with a handle 54- which may be conveniently reached by the operator of the machine. The lever is confined within a bracket 55 which is fixed to the gyrating arm. Said lever is toothed as indicated by the numeral 56 and adapted to engage a pin 57 carried in the walls of the bracket. A spring pressed push rod 53 is provided and adapted to keep the lever teeth in engagement with the pin 57. It is seen how the lever may be used to adjust the length of the hoe arm, the sleeves 50 and the rib 4:9 keeping the correlated arm and gyrating arm in a strong and substantial relation. A coil tension spring 59 has one extremity fixed to the lower sleeve of the hoeing arm and the other fixed to the bracket ll. A pair of arcuate guide members 60 and 61 are provided one upon either side of the associated hoe and gyrating arm, and fixed to the support frame. Said guide members guide and strengthen the structure taking the thrust of the hoe arm as the machine passes down the row.

In the operation of the machine the crank arm is driven through its correlated driving elements a sufficient speed to cause the cutting blade to pass through the row at the proper distance to leave the hilled cotton at the desired spaced distance; the spring will absorb and modify the vibrations and thrusts of the fast moving gyrating and hoeing arm; the arm imparting a gyratory motion to the associated hoeing arm, while the correlated slot 44 and pin 42 compensate for the reciprocating and gyrating action of the hoe arm.

The invention is presented as including all such modifications as properly come within the scope of the followin claims.
